Hi Neil, The ReaderWriter::Options structure has a data file path list built into it, this is checked before the main data file path list stored in the Registry is checked. So if you want a certainly directory checked just put it on your path, either via the ReaderWriter::Options or via the Registry using osgDB::s/getDataFilePathList. You'd typically use Options when you only want to locally set the search path.
